Control registers
(a) Port register AL (PAL)
The PAL register is a 16-bit register that controls reading the pin levels and writing the output
levels of port pins PAL0 to PAL15.
This register can be read or written in 16-bit units.
If the higher 8 bits of the PAL register are used as PALH register, and the lower 8 bits as the PALL
register, however, these registers can be read or written in 8-bit or 1-bit units.
Reset input causes an undefined register content.
